TOOL-TANG.

SPECIFICATION forming part of Letters Patent No. 343,225. dated .Tune 8,1886.

Application tiled February 11, 1886. Serial No. 191,552. (No model.)

To all whom, it may concern:

Be it known that I, JOHN GHANTRELL, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in Tool-Tangs; and Ido hereby declare the following to be a full, clear, and exactdescription ot' the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to the class of tools-- as, for example,tiles-which are provided with^ tangs, ordinarily made integraltherewith, to which the handles are secured, and has for its object toproduce simple, durable, and economical means, whereby the handles maybe attached in such a manner that they will not become loose in use, andthe complicated and expensive construction heretofore used may bedispensed with. In order to accomplish this result, and to adapt atool-tang for ready attachment to a handle, I have devised theimprovement in the construction of tangs, which I will new describe,referring by letters to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a section of a handle with a sheathin elevation, and showing my improved tang engaged thereby; Fig. 2, anend elevation ofthe jaws as in Fig. 1, the tang being in section,showing the manner in which the latter is grasped. Fig. 3 is' anelevation of a tang, showing grooves cut at the corners; Fig. 4, anenlarged cross-section of a tang of this style, taken through one of thegrooves.

In connection with this case attention is called to my pendingapplications, Serial Nos. 178,984 and 178,985, tiled October 5, 1885. mypresent invention being intended to cover tools having tangs alreadyprepared for use in connection with my novel styles of handles. Arepresents the tang of a file or other tool, and B grooves ordepressions therein, each set of grooves being arranged in a straightline around it, which are adapted to be engaged by correspondingprojections upon some portion of t-he toolhandle. These grooves may ofcourse be cut in any suitable manner, that not being of the essence ofmy invention.

This style of tang may be used in connection with any handle soconstructed as to properly grasp it. It is, however, especially adaptedfor use in connection 'with my novel tool-handles described in mypending applications above referred to. In order, however, that myinvention may be thoroughly nnder stood,irrespective of my pendingapplications, I will describe the same in connection with one form oftool-handle.

O in Fig. 1 represents the body of the hann dle, having a centralopening, D, and E the ferrule, which is turned over the end of thehandle and down into said central opening.

F represents a sheath screw-threaded at its lower end,to engagetheinterior of the handle.

G represents jaws, which are preferably made integral with the sheath,and are provided at their outer ends with inclined cutting- I edges H,adapted to engage grooves or depressions B inthe tang.

The operation is as follows: The tang is inserted between the jaws untilthecuttingedges enter depressions B. The combined sheath and jaws arethen screwed into the handle until inclines K on the backs of thejawsare engaged by the turned-over end of the ferrule, whereby thecutting-edges are forced into depressions B, thereby holding the tangfirmly against being turned or removed.

As stated abovefiles having this style of tangs are adapted for use inconnection with any style of handle that will grasp the tang.

I have merely illustrated one style, in order to clearly set forththeobject of my invention.

Having thus described my invention, I Claim- As anew manufacture, a toolhaving an angular tapering tang which is provided with grooves at thecorners oblique to the faces thereof, each set of grooves being inastraight line, so that the tool may be securely grasped and held atdifferent places by jaws, and at the same time is prevented fromturning.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN OHANTRELL.
